Telelogic White Paper Driving Business Success with Software Reuse Leveraging an SCCM Solution for Effective Component Based Development Introduction As enterprise software systems continue to grow in complexity, IT is struggling to find better ways to meet the increasing business demands. With pressure to create higher quality software more quickly and at less cost, enterprise IT must find ways to streamline development. One way that organizations are meeting this challenge is by implementing ways to drive a successful software reuse initiative. The upside to this approach is considerable: devising an effective software reuse strategy enables software development teams to construct enterprise software systems through assembly of reusable parts, and Component Based Development (CBD) serves as a critical enabler of realizing higher degrees of reusability. While CBD is not new, immature technologies and short-term approaches have hindered previous efforts and have soured some on the CBD journey. But that is changing, and many are looking at CBD with fresh eyes. Today, proven technologies and tools exist that allow teams to develop, share, and manage the evolution of their software assets. With many organizations embarking on large-scale Service Oriented Architecture (SOA) initiatives, Component Based Development (CBD) stands to play a critical role in realizing higher degrees of reuse across enterprise services and applications. In fact, CBD is one of the few technologies to have successfully bridged the gap between commercial and open source software development. At present, the open source community thrives on componentization as a major means of achieving high degrees of reusability. Realizing maximum value and return on investment from your enterprise software development initiatives in today’s diverse software ecosystem demands an effective reuse strategy that features CBD as its principle driver. Component Based Development and SOA In many ways, Service Orientation is an evolution of the primary tenets of Component Based Development, and a stated SOA goal is to fulfill mission critical business processes through an orchestration of reusable services. But SOA also represents a significant step forward, in that it offers the possibility of helping IT and business achieve greater alignment through services that expose discreet business functions. While SOA has the potential to increase alignment between IT and business, the services development faces many of the same challenges that software development teams have dealt with for decades. One critical dilemma is preventing problems that arise from the inability to manage change and evolutionary growth. An effective software reuse strategy, achieved through componentization provides a significant benefit in realizing your SOA goals. Let’s illustrate this benefit with a simple example. Figure 1 shows a sample Use Case diagram for an insurance company Claim Management System (CMS). A Customer Service Representative enters the claim upon receiving a notice of loss from the customer. After the claim has been entered into the system, workflow rules dictate to which Claim Adjustor the claim is routed. After receiving the claim, the adjustor can evaluate the loss, enter the claim into their electronic claim file, and eventually process the claim to settlement.
